damage to internal parts of the inverter, etc. Identify the cause of the trip, then remove the
cause and power on the breaker.
● When the protective function is activated (i. e. the frequency inverter switches off with an
error message), take the corresponding corrective action as described in the inverter man-
ual, then reset the inverter, and resume operation.
